SUMMARY:   Suitable for the BCS Mainframe Technology professional Exams for levels 1 and 2 Developer AUDIENCE:   This highly practical course is for all programming staff who are to be involved in Application Development. Based upon the Jackson Structured Programming methodology, this course is aimed at all trainee and experienced programmers. Indeed, anyone who wishes to design and evaluate program solutions before coding will benefit. PREREQUISITES:   No essential prerequisites, however, delegates should have a basic grounding in IT concepts. DURATION:   5 days. Workshop and Lecture based. FOLLOW ON:   COBOL Part 1; Assembler Part 1; PL1 Programming OBJECTIVES:   The course aims to improve staff performance by reducing time spent examining, testing and correcting completed code. Participants will acquire the knowledge and skills to: - Describe and recognise the concepts, stages and functions of the Jackson Structured Programming Methodology. - Use the Jackson Structured Programming Methodology effectively to design logical program solutions. - Design and apply test data to the chosen design. - Understand how to convert the solution design accurately into program code.
